GAS OR FLUID MOTOR.

Specification of Letters Patent.

Patented Alipr., 141, 191%.

Application led February 25, 1913. Serial N o. 750,600.

To all whom it may concern Be it known that I, PAUL GAnTi-I, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Gas or Fluid lvIotors, of which the following is a specification.

This invention relates to motors, and particularly to motors used in meters for measuring the flow of gas, water or other fluids.

The object of the invention is to form an improved motor of the rotary type, embodying a novel construction and arrangement of the valve leading to the meter casing, and the rotary member or wheel driven by the flowing fluid. The valve serves as a bearing for the spindle of the wheel, a glass plate being provided on which the spindle rests.

The invention is illust-rated in the accompanying drawings in which- Figure 1 is a sectional view of the'meter. Fig. 2 is a plan of the wheel which is driven by the flowing gas. Fig. 3 is a top view of the valve.

Referring specifically to the drawings 6 indicates the meter casing, having an inlet at 14 and an outlet at 15, suitably threaded for pipe connections. The upper part of the casing contains the registering mechanism 7, which may be of any suitable construction, and is held in place by a suitable support (Sk Ordinarily the mechanism will be provided with a window or other means to expose the face of the register, so that it can be read.

The registering mechanism is driven by a spindle 8 which extends through suitable openings in the partitions 6a and G", and through a centering bearing at Q0 in a cross arm 10. A circular plate 9 is fastened to the spindle, and at its periphery carries depending curved blades 21 which surround the valve 1l. This valve comprises a cup shaped disk member which seats against the seat 12 when the flow is stopped, and in the top thereof it has a central glass plate 13 against which the lower pointed end of the spindle S bears. A stem 16 projects downwardly from the valve into the inlet pipe, with a guide 16a to hold it in place.

In use when the flow is on, the valve 11 is lifted, and the fluid escaping between the edge of the valve 11 and the seat 12 strikes the blades 2l and drives the wheel, the motion of which is communicated to the spindle S and the registering mechanism above.

The construction permits the wheel to be placed closely adjacent to the valve passage through which the fluid passes, which is advantageous, because the nearer the wheel is to the valve the more exact is the operation of the meter. The spindle bearing 13 on top of the valve gives very little friction and permits the desirable close relation of the wheel to the valve. The weight of the valve serves to keep the velocity of the gas or other fluid constant regardless of its volume, and also as a check to prevent possible back flow of the fluid through the meter.

What is claimed as new is:

In a fluid motor, the combination of a casing having an inlet and an outlet, a spindle, a wheel attached to the spindle and provided with a projecting ring of blades, said spindle having a bearing end depending below the wheel, and a pressure-opened valve controlling the inlet `to the casing and l0- cated within the ring of blades and under the spindle and adapted to liftV under pressure and form a bearing for the lower end of the spindle, and shaped to direct flow radially against the blades, and acting to prevent any back flow through the motor.

In testimony whereof, I do atlix my signature in presence of two witnesses.

PAUL GAETI-I.
